Probably the biggest failure I have done in my save is a incident with my space station. I finally launched the station core up and had a lot of mods on it. The one that caused my catastrophic failure was the B9 pack. I opened the shielded docking platform from this wonderful pack from EVA and my ship began spinning. Not a casual spinning like around 50 m/s spinning. Bill quickly got out from the area s the ship reached greater speeds. Bill was later hit by a solar panel and was flung 70 meters away. I quickly reverted flight and restarted and edited the shielded docking ports so they didn't cause catastrophic disasters.
